You may know the acronym GPS which stands for Global Positioning System, a satellite system owned by the United States. But Global Navigation Satellite Systems are also owned by Russia (GLONASS), Europe (Galileo), and China (BeiDou). Global Navigation Satellite System (GNSS) is a broad term describing receivers that may function using any one of these systems.
Everyday Uses
GNSS receivers process satellite signals to determine the position of the receiver, its velocity and precise time to provide navigation information. These receivers are used by the military but have become common in everyday civilian life in automobile GPS systems, air and nautical systems, heavy equipment, ground navigation for hikers and climbers, spacecraft, trucking, and even to assist the visually impaired.
Do You Have The Time
Precision measurement of time is vital for critical needs around the world. Communications, finance systems, and even the power grid rely on exact measurement of time to synchronize and operate with efficiency. GPS time is accurate and free and provides cost savings for businesses that depend on precision in time, according to website.
Surveyor Uses
GNSS receivers are used to for survey marking, road construction, and building. The best receivers use signals both from L1 and L2 GPS frequencies and can produce accurate measurements as close as one centimeter or less. The best receivers are rugged and easy to use, delivering accurate and fast GNSS data. The user can monitor and configure the receiver using the WEB, WIFI or even SMS.
Many modern devices are available to access any one of the systems owned by different governments. Many of the available receivers used by the surveyor can process signals from many of these systems (GPS, GLONASS, or BeiDou) simultaneously. GNSS may seem like just another acronym, but it’s interesting to note that the world of positioning is broader than GPS. Browse the website for more information.
